Jianjie organic binder for iron ore pellets

Bentonite Extender

Jianjie Bentonite Extender is formulated from multiple water-soluble polymer compounds. With excellent hydrophilicity, complexation capability, and binding performance, it effectively enhances the bonding strength and high-temperature stability of bentonite.

By improving the adhesive properties of bentonite, the extender enables reduced bentonite dosage while maintaining or even improving overall performance. It is suitable for both metallurgical pellet-use bentonite and foundry bentonite applications.
